Long-term supplementation of daily oral 400 μg FA + 100 μg vitamin B-12 promotes improvement in cognitive functioning after 24 mo, particularly in immediate and delayed memory performance. This trial was registered at clinicaltrials.gov as NCT00214682.

The increasing prevalence of chronic disease is a driver of health system reform in most economically advanced nations. A consistent theme within these reforms is building greater patient-centredness into the health care delivery. This study aims to develop an in-depth understanding of the experience of patients and family carers affected by chronic illness that will be the basis on which to propose policy and health system interventions that are patient-centred. Participants struggled with the ongoing tasks of balancing their lives with the increasing demands and intrusion of chronic illness. Their attempts to achieve a balance were seriously hampered by fragmented services, complexity in navigating health services, relationships with health professionals and others, and co-morbidity. Future policy directions include designing models of care and infrastructure that enable patients and their family carers to balance life and illness, and aligning patient-centred care not only within health services but also with community and social support services.

Objective: To describe the evolving roles of practice nurses in Australia and the impact of nurses on general practice function. Design, setting and participants: Multimethod research in two substudies: (a) a rapid appraisal based on observation, photographs of workspaces, and interviews with nurses, doctors and managers in 25 practices in Victoria and New South Wales, conducted between September 2005 and March 2006; and (b) naturalistic longitudinal case studies of introduced change in seven practices in Victoria, NSW, South Australia, Queensland and Western Australia, conducted between January 2007 and March 2008. Results: We identified six roles of nurses in general practice: patient carer, organiser, quality controller, problem solver, educator and agent of connectivity. Although the first three roles are appreciated as nursing strengths by both nurses and doctors, doctors tended not to recognise nurses’ educator and problem solver roles within the practice. Only 21% of the clinical activities undertaken by nurses were directly funded through Medicare. The role of the nurse as an agent of connectivity, uniting the different workers within the practice organisation, is particularly notable in small and medium‐sized practices, and may be a key determinant of organisational resilience. Conclusion: Nurseing roles may be enhanced through progressive broadening of the scope of the patient care role, fostering the nurse educator role, and addressing barriers to role enhancement, such as organisational inexperience with interprofessional work and lack of a career structure. In adjusting the funding structure for nurses, care should be taken not to create perverse incentives to limit nurses’ clinical capacity or undermine the flexibility that gives practice nursing much of its value for nurses and practices.

Background: There is still debate as to which features, types or components of primary care interventions are associated with improved depression outcomes. Previous reviews have focused on components of collaborative care models in general practice settings. This paper aims to determine the effective components of depression care in primary care through a systematic examination of both general practice and community based intervention trials.
